Abstract
The utility model belongs to the field of metallurgical equipment, in particular relates to a middle roller axial locking device in a rolling mill line, which is characterized in that a hydraulic cylinder (2) is respectively fixed at both sides of the stander (6) of a rolling mill; the advancing direction of the hydraulic cylinder (2) is vertical to a middle roller driving side bearing seat (5); the hydraulic cylinder (2) is connected with a baffle plate (3) which is further connected in a sliding chute (4) movably; the hydraulic cylinder (2) drives the baffle plate (3) to freely slide in the sliding chute (4), and the front end of the baffle plate (3) is provided with a dowel head (8); the middle roller driving side bearing seat (5) is provided with a groove part (7) which is in clearance fit with the dowel head (8). The middle roller axial locking device has the advantages of low investment cost, simple and compact structure as well as safe and reliable performance.
Description
Technical field
The utility model belongs to field of metallurgical equipment, particularly the intermediate calender rolls axial locking device in the line of rolling apparatus.
Background technology
In the six-high cluster mill production line, overproof because of supplied materials, produce situation such as band of discontinuance and happen occasionally, the axial thrust load that is produced will cause equipment faults such as traversing cylinder bad seals of intermediate calender rolls or traversing beam bolt cut-out to take place.To this domestic present processing method be: one, change the traversing cylinder sealing of intermediate calender rolls, strengthen traversing beam bolt diameter, strengthen traversing beam rigidity etc.; It is high that the shortcoming of this way is labour intensity height, handling problem time length, frequency is handled in equipment fault; Two, improve by hydraulic system, add means such as ball valve and lock the intermediate calender rolls position; The shortcoming of this way is the leakage that keeps away unavoidable valve and pipeline, thereby causes the deviation of the actual traversing position of intermediate calender rolls; Work a period of time still can cause problems such as traversing cylinder bad seals of intermediate calender rolls and traversing beam bolt cut-out to take place.The production requirement that all incompatibility six-high cluster mill production line speed is fast, output is high, fault rate is low for above-mentioned solution, maintenance time is short.
Summary of the invention
The purpose of this utility model provides a kind of intermediate calender rolls axial locking device, and its cost of investment is low, and is simple and compact for structure, and performance is safe and reliable.
The purpose of this utility model is to realize like this, design a kind of intermediate calender rolls axial locking device, it is characterized in that: the both sides of rolling-mill housing 6 are fixer cylinder pressure 2 respectively, hydraulic cylinder 2 directions of advance are vertical with intermediate calender rolls transmission side bearing block 5, hydraulic cylinder 2 is connected with baffle plate 3, baffle plate 3 is movably connected in the chute 4, hydraulic cylinder 2 drives baffle plate 3 and slides arbitrarily in chute 4, baffle plate 3 front ends have pin head 8, intermediate calender rolls transmission side bearing block 5 has slot part 7, and intermediate calender rolls transmission side bearing block 5 has slot part 7 and pin head 8 matched in clearance.
Have near switch 1 on described hydraulic cylinder 2 end faces.
The utility model is mainly used in six-high cluster mill unit operation line.In six-high cluster mill unit operation line, after intermediate calender rolls is set to the operating position, if situations such as supplied materials is overproof, broken belt take place, the intermediate calender rolls therefore axial force of the receipts of holding will cause equipment faults such as traversing cylinder bad seals of intermediate calender rolls or traversing beam bolt cut-out aborning; By left baffle 3 respectively in left and right sides chute 4 to medial movement, baffle plate 3 pin heads 8 cooperate insertion with intermediate calender rolls left and right sides transmission side bearing block 5 slot parts 7, guarantee device security.It is low, simple and compact for structure that this intermediate calender rolls axial locking device has cost of investment, and safe and reliable, the flexible and convenient operation of performance can be used for various six-high cluster mill production lines.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the utility model example structure schematic diagram.
Among the figure: 1, near switch; 2, hydraulic cylinder; 3, baffle plate; 4, chute; 5, bearing block; 6, rolling-mill housing; 7, slot part; 8, pin head; 9, side plate; 10, intermediate calender rolls drives hydraulic cylinder.
The specific embodiment
As shown in Figure 1: the both sides of rolling-mill housing 6 are installed hydraulic cylinder 2 respectively, hydraulic cylinder 2 directions of advance are vertical with intermediate calender rolls transmission side bearing block 5, hydraulic cylinder 2 is connected with baffle plate 3, baffle plate 3 and chute 4 are flexibly connected, hydraulic cylinder 2 driving baffle plates 3 slide in chute 4 and slide arbitrarily, baffle plate 3 has pin head 8, and pin head 8 cooperates and can insert with intermediate calender rolls transmission side bearing block 5 slot parts 7.When being subjected to intermediate calender rolls fixing on the intermediate calender rolls transmission biside plate 9, intermediate calender rolls drives hydraulic cylinder 10 axial forces behind assigned address, the both sides of rolling-mill housing 6 are installed hydraulic cylinder 2 inwardly action respectively respectively, left baffle 3 respectively in left and right sides chute 4 to medial movement, chute 4 here play the guiding role, baffle plate 3 pin heads 8 cooperate insertion with intermediate calender rolls left and right sides transmission side bearing block 5 slot parts 7, off working state, hydraulic cylinder 2 withdrawals, intermediate calender rolls two side shields 3 pin heads 8 are thrown off with intermediate calender rolls transmission side bearing block 5 slot parts.
Be accurate control, (being the end) has near switch 1 on hydraulic cylinder 2 directions of advance, delivers to hydraulic control system near the position signalling of switch 1, and the chain control of unit is participated in the position of hydraulic cylinder forward-reverse.
Claims (2)
1, intermediate calender rolls axial locking device, it is characterized in that: the both sides of rolling-mill housing (6) are fixer cylinder pressure (2) respectively, hydraulic cylinder (2) direction of advance is vertical with intermediate calender rolls transmission side bearing block (5), hydraulic cylinder (2) is connected with baffle plate (3), baffle plate (3) is movably connected in the chute (4), hydraulic cylinder (2) drives baffle plate (3) and slides arbitrarily in chute (4), baffle plate (3) front end has pin head (8), intermediate calender rolls transmission side bearing block (5) has slot part (7), and intermediate calender rolls transmission side bearing block (5) has slot part (7) and pin head (8) matched in clearance.
